Profile: Frazier showed good plate discipline and respectable power in the minors, so he’s probably a better option in OBP leagues than in traditional batting average leagues, but his third base eligibility is enough to warrant a second look as the position is perilously shallow at the moment. If the Reds go into 2012 healthy and without trading anyone currently on the roster, it's unclear where Frazier plays, but he was a top-50 prospect as recently as 2010, so the Reds probably won't just let him rot. Shallow or mixed league players would be wise to wait until it’s clearer as to how the Reds are going to use him, but for deep keeper leagues or NL-only players, Frazier might be worth stashing based on potential -- and the fact that Scott Rolen isn’t going to play forever.

The Quick Opinion: Having one fewer Yonder Alonsos on the roster makes it more likely that Frazier will get consistent playing time, though he may find it at a number of positions. He’s still most valuable as a third baseman, even if he ends up qualifying as a left fielder in 2012.

Profile: The top five ISOs for third basemen last year consisted of Miguel Cabrera, Aramis Ramirez, Adrian Beltre, Pedro Alvarez … and Todd Frazier. His .225 ISO was the fourth highest among third basemen who had at least 400 plate appearances last year. At 27 years old, he’s hitting his prime and plays in a great ballpark for power hitters. His .354 wOBA was also in the top ten for third basemen last year. Frazier provides upside at a relatively strong position, but fantasy owners should be wary of his tendency to swing-and-miss. His 12.3% swinging-strike rate ranked second to only Pedro Alvarez among third basemen, and his 36.6% O-Swing% shows patience is a bit of an issue. If pitchers adjust in his second full season, he may hurt owners in the batting average department, and we already know he won’t steal many bases. The signing of Jack Hannahan this winter -- and the Scott Rolen rumor -- suggests the Reds may have a quick trigger to platoon him if he slumps at all to begin the season. (JP Breen)

The Quick Opinion: Now that he projects to be the full-time starter, power-hitting Todd Frazier could transition from surprise Rookie of the Year contender to top-fifteen third baseman in your fantasy league.

Profile: It's unclear what Todd Frazier is after two seasons of data. He played clearly over his head during his rookie season, but his decline may have been a bit too extreme in 2013. Frazier showed slightly improved skills at the plate, walking more and striking out less. Despite the improvement, his batting average on balls in play fell from .316 to .269. That suggests he could be in for some improvement. If he can hit .260 with strong power numbers, he can be a useful fantasy asset. But after last season's decline in slugging, it's tough to say if Frazier is capable of hitting 25-30 home runs per season. He'll be useful if the power comes back. Otherwise, he'll likely be lower-tier option at third. (Chris Cwik)

The Quick Opinion: Some bad luck pushed down Frazier's overall line, which could mean he's in for some improvement in 2014. His power will determine whether he's a starter at third, or a lower-tier option.

Profile: Frazier had established himself as a decent third baseman in deeper mixed leagues heading into 2014, but it’s probably safe to say that his breakout campaign, in which he finished second at the position according to Zach Sanders’ rankings, was largely unforeseen. After all, entering his age-28 season, he was just a lifetime .249 hitter who had yet to reach 20 home runs in a major league season. But he blew away all expectations in 2014. He even stole 20 bases — a number that exceeded his lifetime major league attempts heading into the season. Much of the credit belongs to a healthy average batted ball distance of 293.6 feet, and two-thirds of his home runs were smashed at the hitter-helping Great American Ball Park. Unfortunately, Frazier’s success was largely produced in the first half; after the all-star break, the line drives dried up, his ground-ball-to-fly-ball ratio soared by 30%, and his weighted on-base average plunged by nearly 60 points. True, he hit .293 in August, but that was largely due to some batted-ball luck, and the power remained largely absent. Some of his second half issues, perhaps, can be attributed to a Cincinnati offense that all but disappeared around him; indeed, the percentage of pitches he saw in the strike zone dropped by three percentage points over the last three months of the year compared to the first three. For a guy who’s demonstrated an ability to provide pop at a typically shallow position in fantasy, Frazier deserves to have significant value in 2015, but he strikes out too much, it’s unclear whether the steals are legit, and he’s approaching an age when power begins to fade. (Karl de Vries)

The Quick Opinion: Frazier has set a nice bar for his best-case scenario, but fantasy owners would do well to brace for a bit of a drop-off, making him more of a mid-round option than a guy drafted among the best at the hot corner.

Profile: In 2014, Frazier transformed himself from a guy with just acceptable power and a pinch of speed to nearly a 30/20 guy. Naturally, we all questioned how sustainable the home run to fly ball rate spike was, and wondered if that newfound adoration for the stolen base would last. He proved that both skills were here to stay for the most part, at least in 2015. That said, it's impossible to ignore the second-half collapse in both seasons. In 2014 his OPS dropped 146 points after the break, but it was even more stark in 2015 with a 258-point collapse. This matters a lot more in H2H leagues. While his stolen base output did dip, his isolated slugging percentage actually surged to a new career high, thanks to nearly two times as many doubles as he had in 2014. Frazier headlined a three-team trade this winter and will move from one hitter-friendly venue to another. The Reds and White Sox parks sport identical right-handed home run park factors, so he should see little impact from the switch. However, be aware that his career high fly ball and pull rates are likely to decline at least a little bit, which could hurt his power. The fly ball rate jumped 11 percentage points to 48% while the pull percentage was up nine points to 46%. (Mike Podhorzer)

The Quick Opinion: Frazier proved that his 2014 fantasy breakout was no fluke, as he once again delivered both power and speed. He now moves to Chicago and should enjoy hitting in yet another friendly environment that should ensure he remains one of the better third base options.

Profile: Generally speaking, hitting more home runs correlates to better offensive production. Yet despite increasing home run totals over the last three seasons, Frazier's park-adjusted offense (based on weighted runs created) decreased from 22% above league average in 2014 to 15% in 2015 to just 2% last season. I guess 40 bombs just doesn't mean what it used to. Frazier has become an extreme fly-ball hitter, leading the league in fly ball percentage last year after finishing third in 2015. Unfortunately, that makes for a terrible batting average on balls in play, and subsequently a cratering batting average. In fact, his average ranked fifth-worst among qualified hitters in 2016. That Frazier's walk rate jumped to a career-high 9.6% somewhat helps in on-base percentage leagues, but his expected batting average contributions are so low, it's of little solace. Luckily, Frazier is still a well-rounded contributor in the other four categories. Playing in a small ballpark helps his homer, runs, and RBI totals, and even with a declining speed score at age 31, he's still a threat to steal, having swiped 16 bags on average over the past three seasons. Still, runs and RBIs are partly a function of the team around him, which currently isn't very impressive, making Frazier a low-floor, middling-ceiling option at a deep position. (Rylan Edwards)

The Quick Opinion: Frazier continues to hit homers at an impressive pace, but he's also a serious liability in terms of batting average. While still a threat on the bases, consider that he's also a 31-year old who struggles to reach base 30% of the time despite an increase in walk rate. Pay for his 2016 power but not his 2014 breakout. Frazier is a much different player now.
